Also, as used herein, the term "and / or" includes any and all combinations of the associated listed items.
[0021] With the development of wireless communication technology, in order to obtain better transmission efficiency and signal transmission quality, the requirements for antennas are increasing.
[0022] Taking the digital broadcast antenna or digital television (DTV) antenna applied to vehicles as an example, in the related art, due to the influence of the complex structure of the vehicle, the antenna is easily interfered with, which reduces the performance of the antenna.
[0023] Based on this, the embodiments according to the present application provide an antenna that improves the overall gain. As shown in FIG. 1(a), the antenna 100 includes a first radiation element 110, a second radiation element 120, and a parasitic radiation element 130.
[0024] Also, the first radiation element 110 is connected to the ground point as the ground side of the antenna 100, and the second radiation element 120 is connected to the feeding point as the antenna side of the antenna 100.
[0025] The parasitic radiation element 130 is provided at an interval from either the first radiation element 110 or the second radiation element 120 and is used to couple the signals of the first radiation element 110 and the second radiation element 120.
[0026] Next, the first radiation element 110, the second radiation element 120, and the parasitic radiation element 130 in the antenna 100 will be described respectively.
[0027] The first radiating element 110 is a part of the antenna 100 used for grounding. Here, the first radiating element 110 is connected to the ground point and used for grounding. Exemplarily, the ground pad corresponds to the ground point, and the first radiating element 110 is connected to the amplifier via the ground pad and grounded via the amplifier.
[0028] The second radiating element 120 is a part of the antenna 100 used for signal transmission and reception. Here, the second radiating element 120 is connected to the amplification circuit of the amplifier and used for performing amplification processing on the transmitted and received signals. Exemplarily, the feeding pad corresponds to the feeding point, and the second radiating element 120 is connected to the amplification circuit of the amplifier via the feeding pad and can transmit and receive signals.
[0029] The parasitic radiating element 130 is a passive radiating element, that is, it is not grounded to the ground point and is not connected to the feeding point either. Here, the parasitic radiating element 130 is provided at an interval from either the first radiating element 110 or the second radiating element 120, and thereby transmits and receives signals in a capacitive coupling manner.
[0030] As an option, the first radiating element 110, the second radiating element 120, and the parasitic radiating element 130 are all linear conductors. For example, the parasitic radiating element 130 may be a single branch shown in FIG. 1(a), or may include a plurality of single branches as shown in FIG. 1(b), and can be set according to actual needs. In actual applications, the performance such as the bandwidth, impedance, and reception direction (radiation) of the antenna can be adjusted according to the length, number trend, etc. of the radiating element.
[0031] Exemplarily, the antenna is a DTV antenna, the covered frequency band is 470 MHz to 710 MHz, and the corresponding wavelength is 422.5 mm to 638.3 mm. As shown in FIG. 2, the gain of the parasitic radiation element 130 of the DTV antenna in its covered frequency band is higher than the gain of the DTV antenna without the parasitic radiation element 130 in its covered frequency band. In particular, the gain for the middle frequency and high frequency portions is significantly improved.
[0032] In the embodiments according to the present application, the provided antenna includes a first radiation element, a second radiation element, and a parasitic radiation element. Here, the first radiation element is connected to the ground point as the ground side of the antenna, the second radiation element is connected to the feeding point as the antenna side of the antenna, the parasitic radiation element is provided at an interval with respect to either the first radiation element or the second radiation element, and is used to couple the signals of the first radiation element and the second radiation element. In the above antenna, the parasitic radiation element that is not grounded and not connected to the feeding can enhance the signal through the signal coupling between the first radiation element and the second radiation element, compensate for the loss caused by the influence of the environment, improve the overall gain of the antenna, and optimize the performance of the antenna.
[0033] In one embodiment, as shown in FIGS. 1(a) and 1(b), the parasitic radiation element 130 includes a first region 131 provided corresponding to the first radiation element 110 and a second region 132 provided corresponding to the second radiation element 120.
[0034] Taking the application of the antenna to a vehicle as an example, due to the influence of the material of the radiation element and the vehicle type (different vehicle types, different internal structures of the vehicle), parasitic radiation elements 130 with different lengths can bring different gain efficiencies to the antenna 100. Exemplarily, the frequency band covered by the DTV antenna (470 MHz to 710 MHz) is mainly the middle frequency and high frequency, and the length of the parasitic radiation element 130 can be 1 / 4 wavelength of the middle frequency and high frequency.
[0035] The positional relationship between the parasitic radiation element 130, the first radiation element 110, and the second radiation element 120 also affects the gain effect. As an option, the parasitic radiation element 130 can be provided with a part of the region corresponding to the first radiation element 110 and a part of the region corresponding to the second radiation element 120.
[0036] As shown in FIG. 1(a), the first region 131 in the parasitic radiation element 130 is a part of the region provided corresponding to the first radiation element 110, and the second region 132 in the parasitic radiation element 130 is a part of the region provided corresponding to the second radiation element 120.
[0037] In order to improve the gain effect, in one embodiment, the dimension of the second region 132 is larger than the dimension of the first region 131.
[0038] Exemplarily, the first radiation element 110, the second radiation element 120, and the parasitic radiation element 130 are all linear metal conductors, and the length of a part of the region corresponding to the second radiation element 120 in the parasitic radiation element 130 can be made larger than the length of a part of the region corresponding to the first radiation element 110 in the parasitic radiation element 130, that is, the length of the second region 132 in the parasitic radiation element 130 can be made larger than the length of the first region 131.
[0039] In the embodiment according to the present application, in the provided antenna, the parasitic radiation element includes a first region provided corresponding to the first radiation element and a second region provided corresponding to the second radiation element. And the dimension of the second region is larger than the dimension of the first region. In the above antenna, by providing the main part of the parasitic radiation element corresponding to the second radiation element and the minority part corresponding to the first radiation element, the coupling between the parasitic radiation element and the antenna side is strengthened, and the gain effect at the intermediate frequency and high frequency of the antenna is improved.
[0040] In one embodiment, the parasitic radiation element 130 is provided parallel to the first radiation element 110 and the second radiation element 120.
[0041] Here, the first radiation element 110 and the second radiation element 120 are provided in parallel. The parasitic radiation element 130 is parallel to the overall installation direction of the first radiation element 110 and the second radiation element 120. As shown in Fig. 1(a), the first radiation element 110 and the second radiation element 120 are provided in the horizontal X-axis direction, and the parasitic radiation element 130 is also provided in the X-axis direction and is parallel to the first radiation element 110 and the second radiation element 120.
[0042] Note that the parasitic radiation element 130 being installed parallel to the first radiation element 110 and the second radiation element 120 means being parallel in the overall installation direction. The parasitic radiation element 130, the first radiation element 110, or the second radiation element 120 may have some degree of shape bending, as long as the parallelism in the overall installation direction is satisfied.
[0043] Exemplarily, as shown in Fig. 3(a), although the first radiation element 110 and the second radiation element 120 have bending, the overall installation direction is parallel to the parasitic radiation element 130. As shown in Fig. 3(b), although the parasitic radiation element 130 has a certain degree of bending, the overall installation direction is parallel to the first radiation element 110 and the second radiation element 120.
[0044] The distance between the parasitic radiation element 130 and the first radiation element 110 and the second radiation element 120 also affects the gain effect.
[0045] In one embodiment, the distance between the parasitic radiation element 130 and the first radiation element 110 and the second radiation element 120 is 20 mm or less.
[0046] Fig. 4 illustrates the gain situations of the antenna at three different distances. As the distance increases, the overall gain effect on the antenna decreases, and in particular, the gain for the high-frequency part (for example, 550 MHz to 710 MHz) decreases significantly. When the distance between the parasitic radiation element 130 and the first radiation element 110 and the second radiation element 120 reaches the optimal distance, the overall gain effect exerted on the antenna is the best. Exemplarily, the optimal distance may be 8 mm.
[0047] In the embodiments according to the present application, in the provided antenna, the parasitic radiation element is provided in parallel with the first radiation element and the second radiation element. Here, the distance between the parasitic radiation element and the first radiation element and the second radiation element is 20 mm or less. In the above antenna, by setting the installation direction and the distance between the parasitic radiation element and the first radiation element and the second radiation element, the overall gain of the antenna can be improved, and in particular, the gain effect for the high-frequency part of the antenna can be improved.
[0048] Since the DTV antenna has a low covered frequency band and a long wavelength, its size is large (usually 1 / 4 of the wavelength), and when applied to a vehicle glass, it seriously affects the appearance. Therefore, in one embodiment, both the first radiation element 110 and the second radiation element 120 include an annular structure.
[0049] Exemplarily, as shown in FIG. 5, the first radiation element 110 and the second radiation element 120 may exhibit a rectangular annular structure. In the embodiments according to the present application, the specific shapes of the first radiation element 110 and the second radiation element 120 are not limited as long as they are annular structures.
[0050] The coverage frequency band of the DTV antenna is 470 MHz to 710 MHz, the corresponding wavelength is 422.5 mm to 638.3 mm, the 1 / 4 wavelength is 105.1 mm to 159.6 mm, and the relative dielectric constant of the glass is about 7.2. Therefore, when using a linear-structured radiating element for the antenna side and the ground side of the DTV antenna, the length of each radiating element is 47.4 mm to 127.1 mm. That is, the lowest frequency can cover up to 470 MHz, and the length of the single-sided radiating element in the DTV antenna needs to reach 127.1 mm. In order to achieve coverage of the lowest frequency up to 470 MHz by using the first radiating element 110 and the second radiating element 120 with an annular structure, the length of the first radiating element 110 and the second radiating element 120 is preferably within 100 mm. As can be seen from this, in order to achieve the same coverage frequency band, the annular structure can effectively reduce the overall size of the antenna.
[0051] In the embodiment according to the present application, in the provided antenna, both the first radiating element and the second radiating element include an annular structure. In the above antenna, the first radiating element and the second radiating element with an annular structure can effectively shorten the overall size of the antenna compared with the linear structure, reduce the size, centralize and regularize the overall structure of the antenna, and accordingly improve the aesthetics of the entire antenna.
[0052] In one embodiment, as shown in FIGS. 6(a) and 6(b), the first radiating element 110 and / or the second radiating element 120 further includes a connecting element 140. The connecting element 140 is located inside the annular structure, and both ends of the connecting element 140 are respectively connected to the annular structure.
[0053] In order to apply to different vehicle models and maintain the covered frequency band of the antenna, a connection element 140 can be added inside the first radiation element 110 having an annular structure, and the annular structure can be connected to divide the first radiation element 110 into a plurality of annular structures. Similarly, a connection element 140 can be added inside the second radiation element 120 having an annular structure, and the annular structure can be connected to divide the second radiation element 120 into a plurality of annular structures. At the same time, a connection element 140 can be added inside the first radiation element 110 and the second radiation element 120, and the annular structure can be connected to divide the first radiation element 110 and the second radiation element 120 into a plurality of annular structures respectively.
[0054] As an option, one connection element 140 or a plurality of connection elements 140 can be added to the first radiation element 110 and / or the second radiation element 120. Exemplarily, as shown in FIG. 6(a), the same number of connection elements 140 can be added to the first radiation element 110 and the second radiation element 120, or as shown in FIG. 6(b), different numbers of connection elements 140 can be added to the first radiation element 110 and the second radiation element 120. In the embodiments according to the present application, the installation quantity of the connection element 140 is not specifically limited, and it can be set according to actual needs, as long as it can still maintain the original covered frequency band when the antenna is applied to the corresponding vehicle model.
[0055] In the embodiments according to the present application, in the provided antenna, the first radiation element and / or the second radiation element further includes a connection element, the connection element is located inside the annular structure, and both ends of the connection element are respectively connected to the annular structure. In the above antenna, the connection element added inside the first radiation element and / or the second radiation element including the annular structure can be used to adjust the covered frequency band of the antenna, thereby maintaining the original covered frequency band of the antenna without increasing the overall size of the antenna, applying to different vehicle models, meeting the miniaturization design, and improving the convenience of adaptive improvement for different vehicle models.
[0056] In order to intentionally improve the gain of a certain frequency band, in one embodiment, as shown in FIGS. 7(a) and 7(b), the antenna 100 further includes at least one third radiating element 150. The third radiating element 150 is connected to the ground point and / or the third radiating element 150 is connected to the feeding point.
[0057] Exemplarily, as shown in FIG. 7(a), the third radiating element 150 may be connected to the ground point as the ground side of the antenna 100, or as shown in FIG. 7(b), the third radiating element 150 may be connected to the feeding point as the antenna side of the antenna 100.
[0058] The frequency band in which the third radiating element 150 intentionally improves the gain is negatively correlated with the length of the third radiating element 150. Here, a relatively short third radiating element 150 is used to intentionally improve the gain of the high-frequency band, and a relatively long third radiating element 150 is used to intentionally improve the gain of the low-frequency band.
[0059] As an option, the antenna 100 may include a plurality of third radiating elements 150, and the lengths of the plurality of third radiating elements 150 are different, thereby improving the gain for a part of the plurality of frequency bands. Exemplarily, as shown in FIG. 8(a), the antenna 100 includes two third radiating elements 150, both of which are provided on the ground side of the antenna 100 and connected to the ground point. Here, in the figure, the right third radiating element 150 is shorter than the left third radiating element 150. The right third radiating element 150 is used to improve the gain of the high-frequency band, and the left third radiating element 150 is used to improve the gain of the low-frequency band.
[0060] In one embodiment, the antenna 100 includes at least two third radiating elements 150. Here, some of the third radiating elements 150 are connected to the ground point, and some of the third radiating elements 150 are connected to the feeding point.
[0061] Exemplarily, as shown in FIG. 8(b), the antenna 100 includes two third radiation elements 150. Here, one third radiation element 150 is provided on the ground side of the antenna 100 and connected to the ground point, and the other third radiation element 150 is provided on the antenna side of the antenna 100 and connected to the feeding point.
[0062] The number and length of the third radiation elements 150 can be determined based on the frequency band with a relatively low gain effect after the antenna 100 is applied to the corresponding vehicle type, thereby compensating for the gain of the corresponding frequency band.
[0063] In the embodiments according to the present application, the provided antenna further includes at least one third radiation element. The third radiation element is connected to the ground point, and / or the third radiation element is connected to the feeding point. In the above method, a third radiation element is added to the antenna, thereby intentionally compensating for the gain of some frequency bands, relatively evenly improving the overall gain of the antenna, and further improving the overall performance of the antenna.
[0064] In the embodiments according to the present application, an antenna glass is further provided. As shown in FIG. 9, the antenna glass 200 includes a glass substrate 210 and an antenna 100, and the antenna 100 is provided on the glass substrate 210.
[0065] Here, as shown in FIGS. 1(a) to 8, the antenna 100 includes a first radiation element 110, a second radiation element 120, and a parasitic radiation element 130. The first radiation element 110 is connected to the ground point as the ground side of the antenna 100, and the second radiation element 120 is connected to the feeding point as the antenna side of the antenna 100. The parasitic radiation element 130 is provided at an interval from either the first radiation element 110 or the second radiation element 120 and is used to signal-couple the first radiation element 110 and the second radiation element 120.
[0066] In one embodiment, the parasitic radiating element 130 includes a first region 131 provided corresponding to the first radiating element 110 and a second region 132 provided corresponding to the second radiating element 120.
[0067] In one embodiment, the dimension of the second region 132 is larger than the dimension of the first region 131.
[0068] In one embodiment, the parasitic radiating element 130 is provided in parallel with the first radiating element 110 and the second radiating element 120.
[0069] In one embodiment, the distance between the parasitic radiating element 130 and the first radiating element 110 and the second radiating element 120 is 20 mm or less.
[0070] In one embodiment, both the first radiating element 110 and the second radiating element 120 include an annular structure.
[0071] In one embodiment, the first radiating element 110 and / or the second radiating element 120 further includes a connecting element 140. The connecting element 140 is located inside the annular structure, and both ends of the connecting element 140 are connected to the annular structure respectively.
[0072] In one embodiment, the antenna 100 further includes at least one third radiating element 150. The third radiating element 150 is connected to the ground point and / or the third radiating element 150 is connected to the feeding point.
[0073] In the embodiments according to the present application, for the specific structure and function of the antenna 100 in the provided antenna glass 200, reference may be made to the above embodiments, and details will not be repeated here.

In order to improve the aesthetic property, in one embodiment, as shown in FIG. 9, the surface of the glass substrate 210 includes a shielding region 211, and the antenna 100 is attached to the shielding region 211.
[0075] Exemplarily, an ink layer is applied to the surface of the glass substrate 210, a shielding region 211 is formed after the pattern design, and the antenna 100 is attached to the shielding region 211. For example, the antenna 100 is attached to the inner surface of the glass substrate 210 by means such as silver paste printing or (Flexible Printed Circuit, FPC) adhesion. Corresponding to the shielding region 211, the antenna 100 is shielded by the shielding region 211, so that the antenna 100 is not visible from the outside.
[0076] The antenna glass 200 may be applied to a vehicle, for example, glass provided at any position of the vehicle. Exemplarily, the shielding region 211 is provided along the edge of the vehicle window, and the antenna 100 may be provided in the shielding region 211 of the vehicle window. In the antenna 100, the first radiation element 110, the second radiation element 120, the parasitic radiation element 130, the connection element 140, and the third radiation element 150 all extend along the extending direction of the frame of the vehicle window.
